From f1b07a14694be02b2b87e2fe6def6cff2f4bd452 Mon Sep 17 00:00:00 2001 From: Sumeet Pawnikar Date: Fri, 16 Jul 2021 22:09:46 +0530 Subject: thermal/drivers/int340x: Use IMOK independently Some chrome platform requires IMOK method in coreboot. But these platforms don't use GDDV data vault in coreboot. As per current code flow, to enable and use IMOK only, we need to have GDDV support as well in coreboot. This patch removes the dependency for IMOK from GDDV to enable and use IMOK independently.
